Codex is the official design system for Wikimedia, bundled with MediaWiki since version 1.39, offering Vue 3 components, design tokens, and an icon set with language and directionality variants for translatable, accessible interfaces.
Icons ship with built-in language and directionality (LTR/RTL) variants specifically, a concrete answer for any project needing genuinely global, multi-script iconography rather than assuming one icon works identically in every language.
Developers building on MediaWiki or any genuinely multilingual, globally-used platform who need accessible Vue components with real internationalization built in.
It's available both bundled with MediaWiki and as standalone npm packages, so it can be adopted outside a MediaWiki context entirely.
Wikimedia's toolkit for consistent, accessible, and internationalized products.
